To all whom it inay concern:

Be it known that I, MICHAEL Ssi'rz, Whose post' ofiice address isNo. 13 Aussere Laufergasse, Nuremberg, Ba-

varia, in the Empire of Germany, have invented a certain new and useful Method for the Manufacture of Printed T-able-Cloths; and I- d0 hereby declare the fol- Jlowing to be a full, clear, and exact description of the invention, suchas will enable others skilled in the art to which it appertains to make and use the same. I

This invention relates to a method for the manufacture of printed table-cloths. I

. ,Print'rng on tablv cloths, which-is particularly effected [or ad vertisiug purposes, has not hithertdbeen .carried out in a satisfactory manner owing to theabsence of irieans for producing a perfectly iast or washable'impression which is at the same time sufficiently sharp to allow of its being distinctly read under all essential conditions: The various kinds of ink I available for the; purpose were restricted by the fact that caustic ink, though washable, must be avoided owing to the injury which it inflicts on the cloth. It is not practicable to weave the text into the cloth, as is done in the case of ordinary patterns, since the nature of the text varies for different requirements. Embroideriiig and other fancy-work is of course out of the question in view of the fact that-tablecloths, forthe purpose indicated, must 'be produced in large quanpresent' invention Washable, dis- Ac'cording to the 'tinct and thoroughly durable impressions are produced by first'priuting on the cloth with a-s'pecial kind of ink I or color, and thensubj'eetingthe,cloth to the action of 'moderate dry heat=at a temperature not greater than 76 C. The heating of the, cloth is'for the purpose of rendering the ink or color soft, so that it becomes in- 'tinfately combined with the fabric.

The ink used consists of a quick drying material, prefrably stitf polishing varnish, binding agent, prefercoloring matter, the the color desired. I The printing is effected in a press,

ably melted nolopliony, pigs fat, a preserving substance preferably tar and the requisite addition of pulverined latter being selected according to on un-dressed cloth; t

- I am aware that it has been a matter of common knowled'gein the art to which this invention relates to employ a printing means containing a quick drying varnish, hogs" fat and coloring material and to iii the printing color by steaming the printed fabric, but a printing means containing merely the above mentioned ingredients is not sufficiently lasting enough for adhering under the strongwear in washing the printed fabric. In the invention as above described the 0010- phony affords'a binding substances and the taraffords a preserving substance. The-adhesive action of the colophony binds the ingredients of the-printing mass together, and the printing mass to the threads of the fabric, while the tar makes the fabric water tight and protects against rotting. The subsequent heating ('ani not be effected by the known rneansof steaming: because this would not sufiice to melt-the printing mass,

The printed fabrics therefore are exposed to dry-heat in .order to effect the saturation of the threads of the fabric, with the printing mass, the said fabric for the l printing purpose being undressed.

The process is specifically carried out as follows: The design is etched in a known manner on lithographers stone, or zinc and the color is rolled in; then after the printinghas been done in the usual manner in the I not sufficiently durable or not adapted to receive washable impressions of any kind; r p M What I claim and desire to secure by'Letters Patcut, is: p 1 A method for the production of printed table cloths consisting in printing undressed woven fabric with inl: conslsting of pulverized varnish, melted colophony,-pigs fat, tar and pulverized color-in; matter and in subjectll g the fabric thus printed to the action of dry heat up to C.
